Which ordered pair is a solution to the equation? Y=-2x+4

1 answer:

4 0

To find that out, we need to substitute the values of each pair and see which makes the equation true:
y = -2x + 4
and the answer is C. (5, -6), lets substitute:
-6 = -2(5) + 4
-6 = -10 + 4
-6 = -6
which holds true

In Covina, California, the population is 47,000. The population increases 18% every year. Determine how long it will take to rea

Alexxandr [17]

Answer: 8.5 years

Step-by-step explanation:

Hi, to answer this question we have to apply an exponential growth function:

A = P (1 + r) t

Where:

p = original population

r = growing rate (decimal form) =18/100 = 0.18

t= years

A = population after t years

Replacing with the values given:

192,000 = 47,000 (1+ 0.18)^t

Solving for t:

192,000/47,000 = 1.18^t

4.08 =1.18^t

ln 4.08 = ln 1.18^t

ln 4.08 =t (ln 1.18)

ln 4.08 / ln 1.18 =t

8.5 years = t
